Background: It remains unclear whether results differ between a Latarjet procedure performed after a failed arthroscopic Bankart repair and one performed as the primary operation. Purpose: To compare the postoperative outcomes of the Latarjet procedure when performed as primary surgery and as revision for a failed arthroscopic Bankart repair. Study Design: Cohort study; Level of evidence, 3. Methods: A multicenter retrospective comparative case-cohort analysis was performed for all patients undergoing a Latarjet procedure for recurrent anterior shoulder instability. Patients were separated into 2 groups depending on if the Latarjet procedure was performed after a failed arthroscopic Bankart repair (group 1) or as the first operation (group 2). Outcome measures included recurrent instability, reoperation rates, complications, pain, Walch-Duplay scores, and Simple Shoulder Test. Results: A total of 308 patients were eligible for participation in the study; 72 (23.4%) did not answer and were considered lost to follow-up, leaving 236 patients available for analysis. Mean follow-up was 3.4 ± 0.8 years. There were 20 patients in group 1 and 216 in group 2. Despite similar rates of recurrent instability (5.0% in group 1 vs 2.3% in group 2; P = .5) and revision surgery (0% in group 1 vs 6.5% in group 2; P = .3), group 1 demonstrated significantly worse pain scores (2.56 ± 2.7 vs 1.2 ± 1.7; P = .01) and patient-reported outcomes (Walch-Duplay: 52 ± 25.1 vs 72.2 ± 25.0; P = .0007; Simple Shoulder Test: 9.3 ± 2.4 vs 10.7 ± 1.9; P = .001) when compared with those patients undergoing primary Latarjet procedures. Conclusion: Functional outcome scores and postoperative pain are significantly worse in patients undergoing a Latarjet procedure after a failed arthroscopic Bankart repair when compared with patients undergoing primary Latarjet. The assumption that a failed a Bankart repair can be revised by a Latarjet with a similar result to a primary Latarjet appears to be incorrect. Surgeons should consider these findings when deciding on the optimal surgical procedure for recurrent shoulder instability.
